    m= slope so first write the equation y=mx+b where m is slope and b is y-intercept substitute x and y for (-9,1) point

    remember x =something you would draw vertical line (undefined slope when slope is zero you would draw horizontal line

    if the slope is 0 that means that \(y_2 = y_1\) so that \(y_2-y_1 = 0\) and that only occurrs on a horizontal line

    So i know when its 0 its undefined and undefined is vertical line so i just graph it??

    when the slope is zero it wouldn't be undefined

    vertical line = undefined slope horizontal line = (slope =0)

    \[\huge\rm \color{reD}{y} = m\color{red}{x}+b\] replace m with 0 and (x,y) with the point (-9, 1) solve for b

    \(slope = {\color{green}{ m}}= \cfrac{rise}{run} \implies \cfrac{{\color{blue}{ y_2}}-{\color{blue}{ y_1}}}{{\color{red}{ x_2}}-{\color{red}{ x_1}}}\implies \cfrac{0}{something}\implies 0\impliedby defined \\ \quad \\ \begin{array}{ccllll} x&y \\\hline\\ -9&1\\ -1000&1\\ +1000&1\\ \pm \infty&1 \end{array}\qquad y=1\impliedby \textit{horizontal line}\)

    you can write an equation with one point and slope \[\huge\rm \color{reD}{y} = m\color{blue}{x}+b\] \[\huge\rm (\color{blue}{x},\color{reD}{y})=(\color{blue}{-9},\color{red}{1})\]

    substitute y for 1 and x for -9 m=0 \[\huge\rm \color{reD}{1}=-9(\color{blue}{0})+b\] (b is y-intercept) solve for b

    yes right so now we should plugthem into the original equation of slope intercept form \[\huge\rm y=0x+1\] 0 times x= 0 so you have left with y =1 that's what you should graph

    |dw:1440721541175:dw| this one is pretty simple slope is 0 just draw a horizontal line where y =1

    and if the equation is \[\huge\rm y=3x+2\] to graph this equation you should always start with the y-intercept y-intercept is a point where line intersect y-axis

    |dw:1440721805900:dw| y-intercept = 2 so draw a point where y =2

    |dw:1440722012910:dw| \[\rm slope =\frac{ rise }{ run }\] in this equation slope =3/1 \[\huge\rm \frac{ rise }{ run }=\frac{ 3 }{ 1 }\] rise =3 run=1 so i'll go 3 units up from 2 and then one unit to the left side
